IMPROVEMENT IN RAILROAD TRACKS.

Specification forming part of Letters Patent No. 135,667, dated February 11, 1873.

To all whom it may concern:

Be it known that I, ALEXANDER D. Room of Hamilton, White Pine county, State of N evada, have invented an Improved Railroad Trackyand I do hereby declare the following description and accompanying drawing are sufiicient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention orexperiment.

My invention relates to an improved bed for railways, and consists of bearing pieces of peculiar form, on which the rails lie, joined by a jointed rod, and having. transverse braces, as more fully hereinafter described.

Figure l is a perspective View of my invention. Fig. 2 is a transverse section.

A A are two inverted-b0wl-shaped cast-iron bed pieces, upon which the rails of the railroad are secured by means of the ordinary chairs. Each of these im'erted-bowl-shaped bearings has a castiron arm or bar, I), long enough to extend half-way across the track, and the meeting extremities of the arms of the two opposite bowls are united in the middle of the track by alap or other equivalent joint,

as shown at O. The upper surface of the inverted bowl-shaped bearings I make flat so that the chair D can be readily secured to it by bolts. Beneath the rails in each chair I by diagonal iron rods c 6, shown at Fig. 1, so as to join the bearings, and thus give the bed a perfect connection throughout.

The inverted bowl for a base will keep the bed steady and firm on loose sandy or soft ground, owing to the extended surface which the bowl covers. The bowl can be easily raised or lowered and adjusted at pleasure by tamping or removing the earth from under it in the usual way.

The center-coupling will be indispensable for providing a chance for the road to yield under a sudden pressure, and the elastic substance under the rail will prevent rigidity and a too solid foundation, as is the case when the bearing is upon stone, and it will prevent much Wear and tear on the rolling-stock.

The bracing of the ties by transverse rods keeps the bed in place where it is either straight or curved.

I am aware that the bowl-shaped sleepers and the jointed tie are old, and these I do not claim; but

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- The rail and bearin g A, in combination with the hinged bar b and braces e e, substantially as described, and for the purpose set forth.

In witness whereof I hereunto set my hand and seal.
